  • RESONANT FREQUENCY PRESSURE SENSOR
    Publication number: 20080282807
    Abstract: A pressure sensor (S) includes an antenna member (10) that is adapted to be resonantly responsive to a desired frequency of electromagnetic radiation (12). An inductance changing body formed from a compressible dielectric material (14) is positioned in proximity to the antenna member (10). A housing member (16) houses the antenna member (10) in a desired proximity to the compressible dielectric material (14). The compression of the dielectric material (14) changes the effective dielectric constant of the antenna (10).
